Abstract

The invention discloses an alternating-current and direct-current integrated power distribution station. The alternating-current and direct-current integrated power distribution station comprises an alternating-current power distribution system and a direct-current power distribution system which are arranged in a power distribution station room. The alternating-current power distribution system supplies power to the direct-current power distribution system through a 0.4 kV feeder switch cabinet; the alternating-current power distribution system comprises two sets of alternating-current power distribution devices which are connected in parallel through a 10kV section switch and a 0.4 kV section switch; and the direct-current power distribution system comprises two sets of direct-current power distribution devices which are connected through a 750V section switch. According to the alternating-current and direct-current integrated power distribution station of the invention, on the basis of satisfying a conventional alternating-current power distribution function, the access requirement of a direct-current power supply and a load can be met.

Description

technical field [0001] The invention relates to the technical field of distribution station construction, in particular to an AC-DC integrated distribution station. Background technique [0002] The function of the distribution station in the power system is to provide AC power for the lower-level loads, and AC power distribution is routinely used. [0003] However, with the continuous development of DC power distribution technology and the continuous advancement of the carbon neutral process, more and more DC loads such as data centers and charging piles consider using DC power directly, and more and more distributed photovoltaic and energy storage And other DC power sources have emerged the need to connect to the DC system. Therefore, the current single AC power distribution substation can no longer meet the access requirements of DC loads and DC facilities. [0004] Compared with AC power distribution system, DC power distribution has the following advantages: [0005]...
